Picture this: you are deep in an incident review, tracing data access logs across your backup infrastructure, and one question keeps coming up—who actually clicked approve? Cohesity WebAuthn exists to answer that without the endless finger-pointing, spreadsheets, or risky shared secrets.
Cohesity uses WebAuthn, the open FIDO2-based authentication standard, to bring phishing-resistant access into your backup platform. It replaces passwords and OTPs with cryptographic credentials tied to your device. In other words, it proves you are you without making you type anything suspicious into a fake login page. When paired with identity providers like Okta or Azure AD, Cohesity WebAuthn keeps identity verification fully under an enterprise’s control while still giving engineers frictionless access to protected consoles and API endpoints.
The integration flow is simple in principle. When an admin signs in to the Cohesity dashboard, WebAuthn validates their hardware key or trusted biometric signal. That proof travels over established OIDC hooks to identify the session owner. Permissions then map to existing RBAC roles in Cohesity’s policy engine. Unlike legacy tokens or SSH keys, these credentials cannot be phished, exfiltrated, or forged after issuance. You are building a gate that checks identity at the cryptographic level, not the clipboard level.
Quick answer: Cohesity WebAuthn verifies user identity through hardware-bound public key authentication instead of passwords or shared tokens. This stops phishing, simplifies compliance reviews, and raises audit confidence across backup, restore, and replication workflows.
For administrators rolling it out, a few details matter. Make sure registration uses enterprise-managed security keys, not personal devices. Rotate recovery methods along with identity lifecycle events. Verify time sync between Cohesity clusters and your IdP to prevent stale challenge responses. These small habits eliminate most “it didn’t work” tickets before they start.
